11.00 PM EDT: Katrina Moves Across Florida; Projected to Hit Panhandle
From NOAA ... the eye of the hurricane moves southwestward across Miami-Dade County; Katrina is a Category 1 Hurricane, the least intense. The projected path has the hurricane hitting the Florida panhandle. The government projection model breaks down regarding what might happen next; the "more reliable" model, in hindsight, falls apart. (Ellipses are quoted material):
Beyond three days...when Katrina is
forecast to be in the eastern Gulf of Mexico...the models diverge
significantly...suggesting tracks which cover the coast from
Mississippi eastward. The official forecast turns Katrina northward
over the eastern Gulf of Mexico ahead of a strong approaching
trough...on a track which is very close to the global model
consensus. This forecast is rather difficult since one of the more
reliable models...the GFS...shows that the cyclone barely touches
the east coast of florida before moving northward....while the
outstanding GFDL moves Katrina south of due west across extreme
South Florida and the Keys as a very intense hurricane.
